Answer:

From ohms law,

V=IR

R=V/I =12.0/150 =0.08 ohm.

According to Ohm's rule, if all physical factors and temperatures remain constant, the voltage across a conductor is directly proportional to the current flowing through it.

  [tex]V = IR[/tex]

  • where V is voltage
  • I is current
  • R is resistance

Step 1

I = 150A

V= 12.0V

From ohms law

⇒ [tex]V = IR[/tex]

⇒[tex]R = V/I[/tex]

substitute the values of I and V in this equation R = V/I

Step 2

⇒[tex]R = V/I[/tex]

⇒[tex]R=12/150[/tex]

⇒[tex]R= 0.08 ohm[/tex]

The effective resistance is 0.08 ohm
